Introduction
Every year on June 8, the world pauses to celebrate World Oceans Day, a global occasion dedicated to honoring the vast and vital oceans that cover more than 70% of our planet’s surface. In 2025, World Oceans Day takes on renewed urgency and significance under the theme “Wonder: Sustaining What Sustains Us.” This theme invites us to reflect on the awe-inspiring beauty and complexity of the ocean and to recognize the crucial role that wonder — curiosity, exploration, and innovation — plays in inspiring the protection and sustainable use of ocean resources.
As the oceans face unprecedented challenges from climate change, pollution, overfishing, and habitat loss, World Oceans Day 2025 serves as a clarion call for collective action. It reminds us that the health of our oceans is inextricably linked to the health of our planet and our own survival.

The Origins and Evolution of World Oceans Day 2025
World Oceans Day was first proposed in 1992 at the Earth Summit in Rio de Janeiro, a landmark global conference that brought environmental issues to the forefront of international policy. The United Nations officially recognized June 8 as World Oceans Day in 2008, establishing it as an annual event to raise awareness and galvanize action for ocean conservation.
Since then, World Oceans Day has grown into a global movement involving over 100 countries, thousands of organizations, schools, and communities. Each year, a new theme guides the focus of events and campaigns, from plastic pollution to marine biodiversity, climate resilience, and now, in 2025, the power of wonder as a driver of ocean stewardship.
Why the Ocean Matters: The Lifeblood of Our Planet
The ocean is the planet’s life support system. It:
- Covers 70% of Earth’s surface
- Produces over half of the world’s oxygen through marine photosynthesis
- Absorbs about 25% of human-generated carbon dioxide emissions, buffering climate change
- Regulates weather and climate patterns globally
- Supports an estimated 80% of all life on Earth, from microscopic plankton to the largest whales
- Provides livelihoods for more than 3 billion people, especially in coastal and island communities
- Is a source of food, energy, medicine, and cultural identity
The ocean’s health directly impacts food security, climate stability, economic development, and biodiversity. Protecting it is essential for sustaining life on Earth.
The Theme for 2025: Wonder – Sustaining What Sustains Us
The 2025 theme emphasizes wonder — the awe and curiosity that the ocean inspires in us. Wonder is the foundation of scientific discovery, exploration, innovation, and traditional wisdom. It connects us emotionally and intellectually to the ocean, motivating us to protect it.
In an era of growing environmental challenges, wonder reminds us that we are part of something greater than ourselves. It encourages us to look beneath the waves, to understand the ocean’s mysteries, and to innovate solutions that ensure its health and resilience.
Major Threats Facing the Ocean Today
1. Climate Change and Ocean Warming
Scientific data reveals that oceans have reached record high temperatures, with 2024 being the warmest year on record. The ocean absorbs over 90% of the excess heat trapped by greenhouse gases, leading to:
- Coral bleaching and reef degradation
- Disruption of marine ecosystems and species migration
- Rising sea levels threatening coastal communities
- Increased frequency of extreme weather events
Human activities like fossil fuel combustion and deforestation release greenhouse gases, intensifying these impacts.
2. Plastic Pollution
Plastic pollution is one of the most visible and devastating threats to marine life. Over 8 million tonnes of plastic enter the oceans annually, accumulating into massive garbage patches and microplastics that infiltrate food chains.
- More than 75% of all plastic ever produced is now waste.
- An estimated 171 trillion pieces of plastic float in the oceans.
- Plastic harms marine animals through ingestion, entanglement, and habitat disruption.
- It also contributes to chemical pollution and climate change.
3. Overfishing and Unsustainable Fishing Practices
Overfishing depletes fish stocks, threatens endangered species, and damages marine habitats. Destructive techniques like bottom trawling and bycatch cause collateral damage to ecosystems.
4. Habitat Loss and Degradation
Mangroves, seagrass beds, and coral reefs are critical habitats that provide shelter, breeding grounds, and carbon sequestration. Coastal development, pollution, and climate stressors are destroying these vital ecosystems.
Global and Local Actions for Ocean Protection
International Commitments
- The UN Decade of Ocean Science for Sustainable Development (2021-2030) aims to generate knowledge and solutions for ocean health.
- The 30×30 initiative seeks to protect 30% of the world’s oceans by 2030 through marine protected areas.
- The Paris Agreement includes ocean-related climate mitigation strategies.
Community Engagement
World Oceans Day is marked by thousands of events worldwide:
- Beach cleanups removing plastic and debris
- Educational campaigns in schools and communities
- Art and cultural events celebrating ocean wonder
- Policy forums and advocacy pushing for stronger ocean governance
Individual Actions
Everyone can contribute by:
- Reducing single-use plastics
- Supporting sustainable seafood choices
- Participating in local conservation efforts
- Raising awareness on social media and in communities
The 2025 UN Ocean Conference in Nice, France
A major event will take place in Nice on June 8, 2025, coinciding with World Oceans Day, ahead of the 2025 UN Ocean Conference (June 9-13). This conference will bring together world leaders, scientists, activists, and stakeholders to accelerate ocean action.
